126.96.36.199. Configuring Your EMIF IP for Use with the Legacy Debug Toolkit
Connecting an EMIF IP Core to an Intel® Stratix® 10 EMIF Debug Interface
For the EMIF Debug Toolkit to access the calibration data for a Intel® Stratix® 10 EMIF IP core, you must connect one of the EMIF cores in each I/O column to a Intel® Stratix® 10 EMIF Debug Interface IP core. Subsequent EMIF IP cores in the same column must connect in a daisy chain to the first.
There are two ways that you can add the Intel® Stratix® 10 EMIF Debug Interface IP core to your design:
- When you generate your EMIF IP core, on the Diagnostics tab, select Add EMIF Debug Interface for the EMIF Debug Toolkit/On-Chip Debug Port; you do not have to separately instantiate a Intel® Stratix® 10 EMIF Debug Interface core. This method does not export an Avalon® -MM slave port. You can use this method if you require only EMIF Debug Toolkit access to this I/O column; that is, if you do not require On-Chip Debug Port access, or PHYLite reconfiguration access.
When you generate your EMIF IP core, on the Diagnostics tab, select Export for the EMIF Debug Toolkit/On-Chip Debug Port. Then, separately instantiate an Intel® Stratix® 10 EMIF Debug Interface core and connect its to_ioaux interface to the cal_debug interface on the EMIF IP core. This method is appropriate if you want to also have On-Chip Debug Port access to this I/O column, or PHYLite reconfiguration access.
For each of the above methods, you must assign a unique interface ID for each external memory interface in the I/O column, to identify that interface in the Legacy Debug Toolkit. You can assign an interface ID using the dropdown list that appears when you enable the Debug Toolkit/On-Chip Debug Port option.
Connecting an EMIF IP Core and PHYLite Core
If you place any PHYLite cores with dynamic reconfiguration enabled into the same I/O column as an EMIF IP core, you should instantiate and connect the PHYLite cores in a similar way. See the Intel FPGA PhyLite for Parallel Interfaces IP Core User Guide for more information.
